1'0 all whom it may concern: I

Be it known that I, HARVEY HAMILTON' ROBERTS, a:,c1tizen of the United States,.re-

sidin at Lexington, in the county of Fayette and tate of Kentucky, have invented a newand useful Improvementin Electric-Light- Bath Cabinets, of which the following is' a specification.

My invention isin the nature of a novel electric-light-bath cabinet, designed to treat the body with the radiant heat and li ht of electric lam s under variations of di erent colors of lig t and the special application of hi h-frequency currents.

t consists in the novel construction and arrangement of .ceed to describe with reference to the draw,-

I, igure 1 is a front-elevation. Fig. 2 is a plan view, Fig.3 is avertical section'through the cabinet on ines 3 3 of Fig. 4. Fig. 4 is a horizontal section 'on line 4 4 of Fig. 3, and

Fig. ,5 is a detail showing the wiring of the electriclight bulbs of different colors.

The cab' et, as shown, is an upright inclosure with olygonal sides, here shown as a hexagon; ut it may be square, octagonal, or of any other desired shape. As shown, the sides are made of separate panels A A A, constructed of wood and painted white on the inside; but they may be made of sheet metal painted or enameled on. the inside or of any other material.

One of the sixsides of'the cabinet is constructed as a hinged door A, provided with a suitable latch or fastening and having an opening covered by a slide or cover s.

.The to of the cabinet consists of a stationary part l3, Fig. 2, coveringone-half of the hexagon, and two hinged cover-doors B and B, each representin one-quarter of the hexagon. These coveroors are hinged to adjacent side panels of the'cabinet andplose together in the middle on a radial line. The inner edges of the cover-sections B B B are cut away to leave a circular opening I),

through which the head of the patient is allowed to rotrude.

At eac angle of the polygonal cabinet on the inside is arranged a vertical row of electrio-light bulbs a a a, extending from the top to the bottom of the cabinet These lamps are focused tipless lamps of a wellknown construction. Behind each vertical row of lamps is arranged an angular reflector parts, which I will now pro:

the cabinet and whose angles correspond to the angles of the polygon. j

detachably The necks of the .-lamps are fixed in .avertical row of sockets in the anglesof the polygon, and the circuit-wires w w. 10*, connecting with the terminals of each lamp, are contained within vertical hollow pilasters C C C, built'upon the outside of the angles of thecabinet and servin to house .these wires outside the cabinet inc osure and out of contact with any moisture which might exist within the cabinet. These external pilasters also serve to strengthen and rein force the joints of the cabinet and are so built with a removable side as to give ready access to the terminals of the lamps for adjusting,

changing, or repairing the same.

My bath-cabinet isprovided with a stool D, mounted on glass feet, and upon which is connected a coil of heavy wire d, being spiral in form and lying flat upon a board, the spirals of the coil being one inch apart. Thecoil is in turn covered with another board about one-half inch thick, the two boards being attached together and between which is the coil of wire having its terminals pro'ecting from between the boards to the cable (1 from a high-fre uency apparatus. The section of the stoo having the coil of wire is covered with cottonand upholstered with leather. The utility of this arrangement in connection with' the light treatment is the advanta e of having .the additional theraeutic e ects of the high-frequency currents. he therapeutic effect of the high-frequency Patented Oct. 310, 1906. 1

currents is too Well known to need explanautility of the currents has been provenin rheumatism, neursthenia, faulty metabolism, and manychronic diseases. This arrangement gives the advantage of both treatments at the same time. The current being one of condensation no un leasant effect is expe- 'rienced at the time o the treatment.

A footstool D is arranged in the bottom of the cabinetupon the floor, and this is in like manner arranged upon-an insulating-support and carries a fiat horizontal coil (1 of insulatedwire, whose terminals emerge through the side of the cabinet in the form of a duplex cable (1. These two coils in the stool and footstool p'ermit of inductive treatment by the electric current transmitted through the cables d. (P.

In constructing and arranging the electricli ht bulbs they are made 0 different colors 0 glass which succeed each other in regular se uence in the vertical series. Thus the to bu lb will be white, the next lower one re and the next blue or violet. Then follows again the white, red, and blue.

All the white bulbs a are wired on a circuit w, Fig. 5, to themselves, and the terminals of this circuit connect with a switch e, Fig. 2. All the red bulbs a are on a circuit w, Fig. 5, and the terminals of this circuit connect with a switch e, Fig.2, and in like manner all the blue or violet bulbs a. are on a circuit 10 Fig. 5, and its terminals connect with a switch e Fig. 2. This enables me to turn a current onto all the white-bulbs to the exclusion of the others, or onto all the red-bulbs alone, or onto all the bluc bulbs alone,'a nd the distribution ofthe bulbs in the se uence arran ed causes the entire cabinet to e lighted up, rom top to bottom with white light, red light, or blue light, according to the requirements of the case, it being-well known that different colors of light have different therapeutic effects.

In a plying electric current to my cabinet I emp 0y alternating currents of high fre-v quency. The advantage of the treatment by the lights in connection with the high-frequency current is the minimizing of the amount of heat generated, with an intensifying of the erspiration, the soothing effect of the colore lights, and the soothing effect of the high-frequency current.

My cabinet is especially recommended and is serviceable in all forms of rheumatic troubles, neurasthenia, nervous diseases of all kinds, and to increase metabolism, and to relieve catabolism.

The high-fre uency current in the electrotherapeutic fiel I have found to be of great value in relieving the sick, and I am not aware that it has ever before been used in this connection.

I claim- I 1. A bath-cabinet having vertical rows of electric lamps on the inside and external pilasters built upon the exterior of the cabinet immediately opposite each row of electric lamps and containing the circuit-wires of the said lamps.

2. A bath-cabinet made with angular sides and having vertical rows of electric lamps arranged within the interior vertical an les of the cabinet and vertical pilasters app ied externally to the vertical corners of the cabinet and containing the circuit-wires of the electric lamps.

- 3. A bath-cabinet made with angular sides and having vertical rows of electric lamps arranged within the interior angles of the cabinet, vertical reflectors arranged in said angles behind each row of lamps and external pilasters ap lied to the outside corners of the cabinet an containing the circuit-wires of the lamps.

4; A bath-cabinet havin within the same a set of electric lights a stoo with a flat coil of insulated wire arranged within the supporting seat or rest for conjoint electrical treatment.

5. An electric-light-bath cabinet having rows of electric lam s with bulbs of different colors, the colors fol owing each other in constantly-repeated sequence to distribute each color throughout the cabinet, a separate circuit for the lamps of the same color and a switch for each circuit.
